T 0 all whom it may concern:

Be it known that I, ARTHUR .L0raz, a citizen of the United- States ofAmerica, residingin New York, inthe borough of Manhattaii, county andState of New York, have invented certain new and useful Improvements inRibbon Guiding and Alttachments for Type-Writing Machines, of which thefollowlng is a specificationg,

This invention relates to .animfrovedribbon guiding and lifting attaeout: for typewrit-ing-machines,- which""'is fniore specifically'intended to be used in connection with the ribbon-shield of i-theHammond typewriting-machine; and the inventionconsists of a ribbongguideffraine which-is hinged at its front-partto .the frame of themachine, and the arms are pro-. vided at their rear-ends withnprightposts 'for applying the shield andwvith-guiding and retainm devices for'ahe i'ibbon madeintegrally with the rear-ends of the arms of the frame;andthe inyention consists further of means for adjustin the position" ofthe ribbon guide-frame ribbonfrelatively to the printing point .betweenthe shuttle and hammer of. the machine, and, lastly, of means by whichthe ribbon can be locked into lifted position ,for the convenientremoval and replacing of the sanie.

In the accompanyingdrawings,.Figure 1 represents a plan-vlew. ofray-improved rib bon feeding and guiding attachment for typewritingmachines, Fig, 2 is-La vertical Fig. 1. Figs. 3 and 4 are elevations ofthe ribbon and its covering shield and guiding devices, taken resectively from the inner and outer side 0 thesame. Fig. 5 is a plan-viewof one end of the ribbon gui eframe, drawnon a larger scale. Fig. 6 1 avertical transverse section, online 6, 6, Fig. 5, and Fig. 7, a detailview of one of the lifters for the ribbon guide-frame provided with anadjustable knob at its u per end.

Similar letters of reference in icate corre sponding parts throughoutthe different figures of the drawings.

Referring to the drawings a represent-s the anvil, b the shuttle, h t ehammer, s the shield, 1- the ribbon and r -the ribbon s ools of aHammond typewriting-machine.

o the upper part of the frame 1 of the machine, encircling the anvil, isapplied a ribbon guide-frame g which is hinged at its front-part to theframe) and provided between. the sleeves of the hin c with an. in-

clined upwardly-projecting andle g, by V which on being presseddownwardly.;. the

supporting top-plate fgqf the .frame of the-E is attached to theinnerend of the;

machine and provided with ata'pering end 9.

I The ribbon guide-fra'me made approximately of U-shape an rear-portioninbackward direction, the main-portion of the arms being approxinatelyconcentric with the anvil a, and being provided at their front-ends with.downwardly bent platesg having curved lower portions g and flatlaterally-extending handles g by means of which the guide-frame g'can betaken hold. of at either of its rearends for being lifted into aninclined position,'as shown in Fig. 2. The'curved tions g" are providedwith flat upright posts 9 to w ich the bent-over or hooksha ed-ends s ofthe shields are applied in t e usual manner. r

At the inner ends of the downwardly-bent plates 9* are arranged uprightposts g7, the

provided with {curved arms which extendlrfrom' the hinged edges of whichserve for guiding the ribbonb" "clearly in Figs. 1 and 5. The curvedlower portions g of the guide-frame serve for iding the lower edge ofthe ribbon, while t e laterally extending handles g serve'for holdingthe upper edge of the ribbon in position so as to prevent it fromslipping out of the guiding devices while it is moved from one spool tothe other and back again;

The shield s is provided with one or two recesses 8 located at itscenter, one above the other, in case a two-colored ribbon is used,

while one recess 8 in the shield a is used in case a ribbon of one coloris em loyed. The proper position of two-colored ribbons for printing inone color or the other is obtained by means of the usual post p arrangedat one side of the ribbon guideframe, and which is provided with astep-shaped lug for holding the ribbon guide-frame and ribbon in itslower or upper position, according as the one or the other color is tobe used in printing. This holdingpost is well known and forms no part 0this invention.

The shields is further providedat its near I or inner side withupwardly-bent guidelugs s of the usual construction, which serve to holdthe ribbon closely on the shield while it is passed from one spool tothe other and back again. At the center of the shield is furtherarranged the usual indicator-point 8 above the recess 8 r Theguide-devices at the ends of the arms of the ribbon guide-frame are-madeinone integral piece with each other and with the shieldsupporting-post, and dispense thereby with the number of separateribbonguidepieces heretofore used. I

Below the curved arms of the ribbon guide-frame are arranged in theframe of the-machine vertically-guided lifters Zwhich are provided atthe upper screw-threaded ends with interiorly-threaded adjustablebuttons or heads l by which the osition of the ribbon guiderframe andshiel relativel to the printing point can beaccurately a justed. Theheads Z can be adjusted on the lifter-rods Zso that the exact positionof the shield and'ribbon relatively to the printing instrumentalities isobtained.- Eaeh head I is provided with'aknurled rim for convenientlyturning the same for adjusting it on the lifter-rod l. I

By the improved ribbon guide-frame the guiding. devices for the ribbonare considerably simplified and rendered more effective, the adjustmentof the guide-frame relativelyv to the printing devices secured in asimple and effective manner, while the entire guide-frame can be-liftedand held in raised position by which the removal and in sertion of aribbon preparatory to returning it into its proper posit-ionforprinting, is greatly facilitated.

I claim: 1. In a typewrithi'g-machine, a ribbon guide-frame havingcurved arms provided at their ends with guide-plates having posts theribbon-shield, and with inner and outer edges and curved arms providedat their ends with ribbon guide-devices at the inner and outer edges andat the upperjahd lower portions of the same, and posts for attaching theends of the ribbo'ii-covering shield, said guidedevices and structure.

4. In a typewriting-machine, the combination, guide-frame hinged to thesame and provided with means for guiding the ribbon and applying theshield,of lifter-rods below said arms provided with adjustable heads foradjusting the position of the ribbon guide-frame and shield relativelyto the.

printing devices.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing WltIlBSSGS.
